Based on the above, the utility model designs an indoor cable with good heat dissipation performance so as to solve the problems.

Disclosure of Invention

The utility model aims to solve the problems that in the using process of the existing household indoor cable, the rubber protection layer on the surface layer is too thick, so that the heat generated by the inner wire core of the cable can not volatilize outwards smoothly, the whole temperature of the cable is high, and the transmission efficiency of the cable is greatly affected.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides an indoor cable that thermal diffusivity is good, includes a set of sinle silk, the outer parcel of sinle silk is provided with the insulating layer, the outside parcel of insulating layer is provided with the shielding layer, the equidistant fixed supporting shoe that is provided with of surrounding distribution in the outside of shielding layer, the gas pocket has been seted up in the middle part of supporting shoe, the fixed parcel in the outside of supporting shoe is provided with the protective layer, the equal embedded steel wire that is provided with in central upper and lower part of protective layer, the heat conduction groove has been seted up to the protective layer of steel wire both sides.

Preferably, the air holes on the supporting blocks are distributed in a linear equidistant arrangement, so that the air around the shielding layer can circulate while the shielding layer is supported.

Preferably, the supporting blocks are distributed around the shielding layer at equal intervals to form annular cavities, so that heat around the shielding layer can be mutually circulated and transferred, the inner ends of the heat conducting grooves are communicated with the cavities around the shielding layer, and part of heat can be taken away to the end parts through steel wires to dissipate heat.

Preferably, the protective layer is a flat rubber sheath, so that the wear resistance of the outer layer of the cable is improved.

Preferably, the wire core is a round solid copper conductor, so that the power transmission conductor can transmit electric energy with high efficiency.

Compared with the prior art, the utility model has the beneficial effects that:

(1) According to the utility model, the supporting blocks are arranged on the outer side of the cable at equal intervals in a surrounding manner, so that the annular cavity is formed between the shielding layer and the protective layer, heat on the outer side of the shielding layer can flow freely in the cavity between the shielding layer and the protective layer, heat dissipates from the notch at the end part of the cable along the cavity, meanwhile, the two steel wires are arranged in the center of the protective layer, so that the cable has a stretching-resistant effect, and meanwhile, the heat in the cavity can be absorbed by the steel wires to dissipate heat from the end part due to better metal heat conductivity, so that the heat dissipation of the whole cable is improved, and the popularization of the cable is facilitated.
